OK, thanks. I tried heat but next time I will try a bit more.

A couple years ago I bought a DB4002 pass cavity and noticed it rattled when I picked it up to move it around. It worked fine, but being curious I opened it up. I found what I would guess to be a tablespoon of solder droppings in the bottom. It was interesting. Apparently loose metal laying at the bottom of a cavity doesn't adversely affect its operation, so long as it is operated in an upright position. 73, Paul N1BUG
